To make a long story short, EA claims that there will be changes made to the game that you saw in the beta, including a number of balancing tweaks and new features to make it easier for people to play together as a team. The brunt of the post specifically addressed Star Wars Battlefront 2’s loot crates and the contents within said crates, stating that “the complete system was not in the Beta and will continue to be tuned over time.” The full list of intended “changes” are as follows:

There are many things you can earn in the game, including weapons, attachments, credits, Star Cards, Emotes, Outfits, and Victory Poses.
As a balance goal, we’re working towards having the most powerful items in the game only earnable via in-game achievements.
Crates will include a mix of Star Cards, Outfits, Emotes or Victory Poses.
Players earn crates by completing challenges and other gameplay milestones, or by purchasing them with in-game credits or Crystals, our premium currency.
If you get a duplicate Star Card in a crate, you will get crafting parts which you can then use to help upgrade the Star Card of your choice.
And lastly, you have to earn the right to be able to upgrade Star Cards and unlock most Weapons. You can only upgrade or unlock them if you have reached a high enough rank, which is determined by playing the game.
